原题是:The ratio of blue marbles to green marbles in a bag is 2 to 5.there are 25 green marbles.How many marbles in which color would you have to add to make the ratio 1 to
题意如下:在一个袋子里面,蓝色的弹珠和绿色的弹珠的比例为2:5,绿色的弹珠有25个.问:要增加哪种颜色的弹珠使得袋中两者的比例为1:增加多少?
(-)设增加的是蓝珠.增加前蓝珠的比列占总弹珠的2/7=8/28.增加后若蓝色:绿色为1:3,则蓝色占总弹珠的1/4=7/28
已知在任何一个(注意是a)袋子里蓝弹珠和绿弹珠的比率(ratio)是2:5。 现在绿弹珠有25个。 问你要加多少个什么颜色的弹珠 来达成这个比率 25/5=5 5*2=10.
题目是说 蓝石头:绿石头= 2:5
现在有绿石头 25 块
问袋子里应该有什么颜色的石头多少块满足题目的已知条件
应该有蓝石头 10块
